    摘要： A flexible glass fiber reinforcement material has microwave-sensitive or ultraviolet sensitive binder added and is formed into a desired shape. Selected electromagnetic energy (microwave or ultraviolet) is then applied to cure and rigidize the binder. A mold for shaping the reinforcement material comprises a mold cavity defined by microwave or ultraviolet transparent material divided into separate and separable mold parts and, for microwave applications, each part carries one half of a split microwave waveguide which directs microwave energy to cure the binder resin when the mold is closed. For ultraviolet applications, an ultraviolet source (or sources) is located in the mold. Energetic stitching of a reinforcement rib is performed by applying a binder resin to the rib at at least one location, placing that location into contact with a preform and curing the binder resin to bond the parts together.

    摘要： Capitalizing on the unique feature of our induction heating workcell that permits rapid and controlled heating and cooling of a workpiece within a wide temperature range permits combining several manufacturing operations into a single heating cycle to save time, energy, capital, touch labor, and factory space. For example, we can combine superplastic forming (SPF) with brazing, two operations that occur at temperatures that differ by about 150-200.degree. F. (85-105-C.) or more, to produce quality parts. Or, we can combine SPF with .beta.-annealing; of titanium. Finally, we can combine forming, brazing, and annealing into an economical single cycle. Illustrating our combined cycles, we produce multisheet SPF parts with braze joints at selected locations with improved energy efficiency and at lower cost by heating the multisheet pack to its superplastic forming range below the melting point of the braze alloy, superplastically forming the pack to define braze joints having unmelted braze alloy; increasing the temperature to the braze temperature of the braze alloy, and cooling the pack below the superplastic range to freeze the braze alloy in the braze joint.

    摘要： An arrangement for molding a front or back polystyrene mold half which is used, with a second complementary back or front mold half, for subsequent molding of a soft contact lens such as a hydrogel soft contact lens. Each mold half defines a convex curved surface and a concave curved surface spaced therefrom, with one of the surfaces defining an optical quality curved surface for the soft contact lens. A heated molding machine introduces molten polystyrene through a hot runner system to a plurality of mold cavities, each of which defines an optical quality curved surface and also a second noncritical surface. The optical quality surface of the mold cavity is positioned further away from the heated hot runner side of the mold than the second surface, which allows faster cooling of the optical quality surface of the mold cavity. Each mold cavity has a first insert on the optical quality side of the mold cavity and a second insert on the second side. Each of the first and second inserts has a circumferential cooling passageway defined therearound or in proximity for the first inserts, and also includes a bubbler positioned internally therein. Coolant is circulated in a turbulent mode through the circumferential passageways and also through the bubblers against inner surfaces of the insert to provide rapid cooling of the mold cavity.

    摘要： Glass fiber mats are made for subsequent use in preforming for an RTM or SRIM molding process, for example, such that the binder applied to the mat has two distinct curing stages. In the first stage, a partial cure is provided by visible light upon a free radical generation in response to a photoinitiator mixed in the binder in an exact ratio to give a predictable increase in viscosity to that of a semi-solid so that the fibers are sufficiently bound for subsequent handling, but not sufficient to complete a cure, while leaving a second stage ready for a final cure which is achieved by the use of a cationic-type second photoinitiator which is sensitive to ultraviolet light. During the second curing stage, the mat is formed into a three-dimensional shape of a desired end product and cured with ultraviolet radiation while still in the mold, to obtain a rigid three-dimensional preform structure.

    摘要： An apparatus and method for removing a molded ophthalmic lens from between the mold portions in which it is produced. A source of intense electromagnetic radiation, preferably a carbon dioxide (CO.sub.2) laser of about 80 Watts at a wavelength of 10.6 .mu.m, is applied to at least one of the mold portions. The exposure of the mold portion to the laser is between one half and one second. Differential expansion of the heated mold polymer relative to the cooler polymer shifts one surface with respect to the other, and the shear force breaks the polymerized lens polymer mold adhesion and assists in the separation of mold portions. The greater the temperature gradient between the surfaces of the mold portions, the greater the shearing force and the easier the mold portions separate. The heated back mold portion is promptly removed so that very little energy is transferred to the polymer lens, avoiding the possibility of thermal decomposition of the lens.
